ABSTRACT:
A method of copying magnetic tapes having a message information track and a control track with supplementary information formatted as a digital word encoded as a plurality of successive data bits. The method includes the steps of playing the tape and reproducing the message track and the control track. The message information is coupled to a second playback/record device for recording. The plurality of successive data bits reproduced from the control track is stored in a digital memory to decode the digital word. The stored digital word is transferred to the second playback/record device and is reencoded as a plurality of successive data bits and recorded in the control track of the second playback/record device.
